With losses in his last two fights, Manny Pacquiao is no longer the elite fighter he once was. And once you drop out of the elite ranks, others start taking shots at you they may not have before. Case in point, Jorge Arce, who says Pacquiao has to be using some sort of performance-enhancing supplements.

"Pacquiao is getting something, that’s for sure,” Arce said told boxingscene.com. “He never comes up positive during drug tests, so it is logical that he is using something that is legal or not detectable in his urine.

"Because I remember when Pacquiao did not want to fight Floyd Mayweather, because Mayweather said that he wanted to have doping tests involved in their fight and Manny refused to have them."

It may seem odd to accuse a fighter on a losing streak of using artificial means to improve himself, but Pacquiao was considered by many to be the best pound-for-pound fighter in the world until his recent skid.

Arce was a champion in four weight divisions before retiring in December.
